SystemCodeDisplay (en)DefinitionJSONXML
https://haau3.com/fhir/CodeSystem/medlist-evidence  recent-dispenseRecent dispenseA dispense of this medication was recorded recently enough to count it as current.
https://haau3.com/fhir/CodeSystem/medlist-evidence  active-orderActive orderAn order for this medication is active and was written recently enough to count it as current.
https://haau3.com/fhir/CodeSystem/medlist-evidence  undated-orderUndated active orderAn order for this medication is active but carries no date, so its recency could not be judged. The entry counts as current on the order's status alone.
https://haau3.com/fhir/CodeSystem/medlist-evidence  patient-reportedPatient-reported useUse of this medication was reported by the patient or by someone acting for them, such as a family member, recently enough to count it as current.
https://haau3.com/fhir/CodeSystem/medlist-evidence  reported-useReported use from a source of recordUse of this medication was reported by a source of record, such as a clinic, a pharmacy or a health plan, recently enough to count it as current.
https://haau3.com/fhir/CodeSystem/medlist-evidence  undated-reportUndated report of useA source states that this medication is in use but carries no date, so its recency could not be judged. The entry counts as current on the statement's status alone.
https://haau3.com/fhir/CodeSystem/medlist-evidence  course-completedCourse completedA source states that this medication's course is complete: a completed status, or an end date that has passed.
https://haau3.com/fhir/CodeSystem/medlist-evidence  prescription-expiredPrescription expiredThe only support for this medication is an order old enough that it no longer counts as current, with no dispense to corroborate it.
https://haau3.com/fhir/CodeSystem/medlist-evidence  order-stoppedOrder stoppedAn order or statement for this medication was stopped by its source.
https://haau3.com/fhir/CodeSystem/medlist-evidence  order-cancelledOrder cancelledAn order for this medication was cancelled by its source.
https://haau3.com/fhir/CodeSystem/medlist-evidence  order-on-holdOrder on holdAn order or statement for this medication is on hold at its source.
https://haau3.com/fhir/CodeSystem/medlist-evidence  patient-not-takingPatient not takingA source states that the patient is not taking this medication.
https://haau3.com/fhir/CodeSystem/medlist-evidence  intendedIntended, not startedA source states that this medication is intended and has not been started.
https://haau3.com/fhir/CodeSystem/medlist-evidence  conflicting-sourcesConflicting sourcesThe source records disagree about this medication's status. The entry carries the status haau3 concluded, and the other signals are listed beside this code.
https://haau3.com/fhir/CodeSystem/medlist-evidence  stale-dataStale dataEvery record of this medication is too old to support a conclusion about its current status.
https://haau3.com/fhir/CodeSystem/medlist-evidence  insufficient-signalInsufficient signalThe records carry nothing that supports a conclusion about this medication's current status.
https://haau3.com/fhir/CodeSystem/medlist-evidence  rxnorm-not-heldRxNorm code not in the held releaseThe medication's RxNorm code is absent from the RxNorm release this list was built against, so it was kept as stated and not resolved to a clinical drug.
https://haau3.com/fhir/CodeSystem/medlist-evidence  rxnorm-not-clinical-drugRxNorm code is not a clinical drugThe medication's RxNorm code names an ingredient, a brand name or another level that does not resolve to one clinical drug, so no clinical-drug coding was added. The entry was matched on the code as stated.
https://haau3.com/fhir/CodeSystem/medlist-evidence  brand-foldedBrand folded to genericA branded source record was folded into this entry's generic clinical drug. The branded coding is kept on the entry beside the generic one, so the brand a source named is not lost.
https://haau3.com/fhir/CodeSystem/medlist-evidence  brand-requiredBrand requiredA source order says the branded product must be dispensed as written, and the records do not show whether the brand or its generic is the one in use, so the brand and the generic are listed as their own entries. Each carries this code.
https://haau3.com/fhir/CodeSystem/medlist-evidence  no-rxnormNo RxNorm codeNo source record for this medication carries an RxNorm code, so no clinical-drug coding was added.

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
System The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance)
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
